TERRA NOSTRA DIAGNOSIS, THE NEW KIDS IN TOWN and ROCK GIFTS are part of a system based on Biomimicry rules and the use of matter, in this case sandstone. This stage of the system was all about using materials readily available (I have a collection of paper) and getting feedback. In addition, I have been looking into indigenous cultures, and because I live in an urban setting - London - I looked at the consumerist nature of this city and used it to my advantage (another principle of Biomimicry is to replicate strategies that work - in this case the aim was to engage people's attention).
